kirkwood: support Linksys boot counter on EA[34]500 

This is done with existing code from the WRT1900AC port.
It makes sure the "auto_recovery" bootloader option is set,
and resets the s_env boot counter after a successful boot.

This gives users without a serial console connection some
measure of safety.
